Thermal energy module

Abstract

The invention comprises a Thermal Energy Module comprising a tank adapted to hold water or other heat transfer medium (such as water), a water loop for introducing the heat transfer medium and removing the heat transfer medium, and a refrigeration loop comprising a heat exchanger further comprised of an inlet manifold, a heat transfer structure (such as a micro channel or pipe-in-plate panel) and an outlet manifold wherein the heat exchanger is adapted to transfer thermal energy between the heat transfer structure and the heat transfer medium. The Thermal energy Module may be utilized as a component of a heating and cooling system. Such a Thermal Energy Module may be used to store thermal energy during the day and return it during the evening. Additionally, such a Thermal Energy Module may be implemented as an array of such modules and such array of modules may be adapted to fit within the walls of a building or structure.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to cold and hot thermal energy storage systems as well as using such systems to optimize and reduce the electric and natural gas energy consumption of a building.[0003]2. Description of the Prior Art[0004]Improving the energy efficiency of building comfort systems has become progressively more important due to rising energy costs as well as increased awareness and concern over global warming as a result of humanity's rising consumption of carbon fuels for electrical energy generation, direct burn heating, and domestic hot water appliances. One area where these concerns can be addressed is through leveling demand by shifting some of the load during peak hours of a day to off-peak times, thereby eliminating the need to build and run expensive peak generator turbines. These turbines are costly to build, install and operate and are typically used for only a very limited number of hours during t...

AI Technical Summary

Benefits of technology

"The present invention provides a system for storing both cold and hot water energy using solar heaters. The system has a high level of energy efficiency by retaining and reusing the extracted heat energy, rather than dissipating it into the atmosphere. The system also provides a higher level of comfort by gradually modulating the cooling and heating capacity and maintaining accurate temperature set points. The main part of the invention is a Thermal Energy Module (TEM) which comprises an insulated flat tank with a flat heat exchanger located inside. The heat exchanger is designed to prevent water on the tank from freezing during the ice generating process. The TEM can be incorporated into building walls and can simultaneously work in different modes. The invention has various other advantages such as providing a sustainable and cost-effective solution for energy storage and utilization."

Problems solved by technology

These turbines are costly to build, install and operate and are typically used for only a very limited number of hours during the hottest days of the year.

The problem is typically this equipment is required to operate during the day, due to the lack of cost-effective, efficient energy storage.

And worse yet, the resulting demand in electricity consumption peaks requiring the use of low-efficiency gas turbine peak generators.

These systems are very complex, bulky, expensive and difficult to scale down for use in small commercial buildings or residential applications.

These types of systems are better suited for smaller buildings but they too suffer from being too complex, expensive and bulky for small businesses and homes.

Moreover, such systems do not provide a high level of comfort due to their inherent deficiency of controlling temperature by cycling the system on and off.

Also, these direct expansion systems can be used only for cooling purposes and are very difficult or impossible to combine with solar heating solutions which are becoming increasingly more important in energy conservation strategies.
